MQTT Sparkplug B is the modern way to move industrial data from the edge to the cloud - lightweight, publish-by-exception, and built for unreliable connectivity. This guide explains how Merobix ingests Sparkplug B, so edge gateways at remote oilfield sites can feed a cloud dashboard efficiently.
Short version: Merobix subscribes to MQTT Sparkplug B, so an edge gateway that publishes field data by exception can feed the cloud platform directly. Adopting it can be as simple as pointing Merobix at the same broker your edge nodes publish to - efficient on cellular, with no inbound firewall rules.
MQTT is a lightweight publish/subscribe protocol; Sparkplug B is the industrial specification on top of it that defines how devices, tags, and state are represented and published by exception. It suits remote sites because it publishes only on change (saving cellular data and battery), connects outbound to a broker (no inbound firewall rules), and handles connection state cleanly. See what IIoT is and edge computing for context.
If you already run edge gateways publishing Sparkplug B - common with modern IIoT and an edge SCADA product deployments - Merobix subscribes to the same broker, so migration or expansion can be as simple as adding a subscriber. Where you do not yet have MQTT, a Merobix cellular gateway can read local devices and publish to the cloud on your behalf.
Yes. Merobix subscribes to MQTT Sparkplug B, so if your edge gateways already publish to a broker, Merobix can consume the same feed - often as simple as adding a subscriber, with no field changes.
It publishes by exception (only on change plus a heartbeat), which conserves cellular data and battery, and connects outbound to a broker so no inbound firewall rule is needed. That suits remote, low-power oilfield sites well.
A Merobix cellular edge gateway can read your local devices (Modbus, DNP3, etc.) and publish to the cloud, so you get the benefits of edge publishing without building an MQTT stack yourself.
